Abstract

The present invention proposes a method for offline upgrading virtual machine mirror images. The method comprises: an mirror image security server collecting virtual machine mirror images, and extracting and storing the information of the collected virtual machine mirror images; and the mirror image security server executing an upgrade operation of virtual machine mirror images in an offline way based on the information of the collected virtual machine mirror images. The method for offline upgrading virtual machine mirror images disclosed in the present invention has higher upgrade efficiency and is capable of upgrading the virtual machine mirror images in an offline way.

Description

Technical field [0001] The present invention relates to an offline upgrade method, and more specifically, to an offline upgrade method of a virtual machine image (the "offline upgrade" used in this article means: the virtual machine image is upgraded without starting the virtual machine). Background technique [0002] At present, with the increasingly widespread use of computers and networks and the increasing variety of business in different fields, cloud computing environments have become more and more common and important. Generally, there are a large number of offline virtual machine images (or virtual machine templates) in a cloud computing environment. Therefore, it is very important to upgrade (ie patch) the offline virtual machine images (or virtual machine templates). [0003] In the existing technical solutions, the following two methods are usually used to upgrade the offline virtual machine image: (1) After the user generates the virtual machine, it is upgraded online; ...
